2 transistors are shorted on Tia

As a straight up replacement, no - the drain current is lower (22A vs 40A.)

You can't. Order the proper transistors from say Marco.

Just curious, can't you get a new Aux board from Stern under warranty?

Further analysis:

The STP22NE10L is rated at 22amps, 100v.
The STP40NF10L is rated at 40 amps, 100v
If you have IRL540N as your 22NE10L replacements (this is what most vendors sell) these are rated at 26 amp, 100v.

It seems unlikely that stem is driving these resistors at full 100 amps. The fuses are what? 5-8amp? While your resistor is weaker than what was used, it may work. Also, in spiderman, stern drives the same doc ock magnet as used in wolverine with the 22NE10L from the main power driver board.

Swapping in either of these will probably get you up and running while you wait for stern to ship a replacement board. I'd try it.

Does Stern require sending the old board back on a warranty replacement? If so, and he does the swap will he have problems?

They want your board back. But, they send you your board first and don't take a credit card or anything. We have three total boards from pdxmonkeys two replacements. Feel free to hack it up as you want.

I've redone the DE magnet board (which suffers from similar issues) and this one looks to be nearly identical in design.

Anyone want to be a new product tester and send me their bad aux board?

I'm sending the aux board with 2 bad transistors back to Stern and Asking them to overnight a replacement. The heat sinks made it a tough job. Thanks guys! Your help seems better than Stern's.
